One of the most eye-catching effects in miniature painting is source lighting, where a glowing object casts light on the rest of the miniature. Especially in the fantasy and science-fiction genres, it’s a great way to show that a sword is imbued with magical energy, or a plasma cannon is charged and ready to fire. Let’s face it: glowing weapons are just cool. This technique is often called “object-source lighting” (OSL) by figure painters, as the source of the light is represented on the miniature (an “object-source”).
Pulling off believable glow effects is tricky, however, and there are many examples of poorly done lighting effects on the internet. In this article, I will show a step-by-step sequence of how I paint source lighting effects, using a Cryxian Slayer by Privateer Press as the demo mini. I’ll also provide plenty of tips and additional examples to help you give your models that eye-catching glow.
